CYTOLOGICAL AND NOMENCLATURAL NOTES ON THE MESOAMERICAN SPECIES OF ACIOTIS (MELASTOMATACEAE)

A review of the Mesoamerican species of Aciotis is presented to facili tate the transfer of Spennera alata, an earlier name for the largely C entral American species heretofore known as A. Le-yana. Original chrom osome counts of n = 30 are reported for two species, A. alata and A. r ostellata, together with brief descriptions, distributional notes, and a regional key to the three Mesoamerican species. Based on a prelimin ary evaluation of reported chromosome counts, x = 10 appears to be the probable base chromosome number of Aciotis.
